Answer:
Mammals first appeared
Explanation:
The dinosaurs became extinct one million years after the Cenozoic era started. The mammals first appeared as the modern culture first appeared in that era.
<h2>Answer is option "2"</h2>
Explanation:
- Steroid hormones are a gathering of hormones, got from cholesterol, from the class of mixes known as steroids. They are emitted by the adrenal cortex, testicles and ovaries, and by the placenta during pregnancy. Based on their receptors, steroid hormones have been ordered into five gatherings: glucocorticoids, mineralocorticoids, androgens, oestrogens and progestogens.
- Puberty is the point at which young ladies' bodies and psyches develop and they develop into young ladies. This typically begins when a young lady is around 10 years of age. Some of the time, however, an a lot more youthful young lady begins to give the indications of puberty. This is called intelligent (pre-KOH-shuss), or early adolescence (PU-ber-ty).
- Hence the right answer is option 2 Premature puberty in girls in the area".
I believe this is done to ensure accuracy. DNA paternity testing involves the use of DNA profiling to determine whether two individuals are biologically parent and a child. The test establishes genetic proof whether a man is the biological father of the individual in question. There is need for use of more than one loci probes to make sure there is no error and that the results are 100% accurate.
Answer:
The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)
Explanation:
Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:
Blood type AB - iAiB
Blood type A - iAiA or iAi
Blood type B - iBiB or iBi
Blood type O - ii
According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:
iBi = iB and i
iAi = iA and I
Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:
- type AB (iAiB)
- type A (iAi)
- type B (iBi)
- type O (ii)
Carbon and hydrogen.
The simplest group of organic molecules are the alkanes which have only these 2 elements. Eg methane, CH4.
